The Dollar Index is on track for a further weekly gain - its fourth in five weeks - of nearly 1%. It gained 0.1% on the day, hitting 92.699. The greenback has strengthened broadly since the U.S. Federal Reserve surprised markets last month by signalling it could tighten policy earlier than expected to curb inflation. The rallies during this week still hint for a short term trend shift to the upside. Look for attempts to extend rallies to the 0.9300 levels, when broken 0.9343.
